The pump sound pressure level has been updated to an Equivalent Continuous
Sound Level (LAeq) to meet the intent of ANSI S1.13-1971, CAGI-PNEUROP S5.1
using four microphone locations.
GENERAL DESCRIPTION
The 9:1 ratio is an expression of the relationship between the eec-
tive air motor area and the eective lower pump area. When 150 p.s.i.
(10.3 bar) of air pressure is supplied to the air motor, the lower pump
end will develop a maximum 1350 p.s.i. (93.1 bar) of uid pressure (at
no ow). As the uid control is opened, the ow rate will increase as
the air motor cycle rate increases to keep up with demand.

OPERATING AND SAFETY PRECAUTIONS
WARNING
HAZARDOUS PRESSURE. Do not exceed maxi-
mum operating pressure of 1350 p.s.i. (93.1 bar) at 150
p.s.i. (10.3 bar) inlet air pressure.
Pump Ratio X = Maximum Pump
Inlet Pressure to Pump Motor Fluid Pressure
Pump ratio is an expression of the relationship between the pump motor area
and the lower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure
is supplied to the motor of a 4:1 ratio pump, it will develop a maximum of 600 p.s.i.
(41.4 bar) uid pressure (at no ow) - as the uid control is opened, the ow rate
will increase as the motor cycle rate increases to keep up with the demand.
WARNING
Refer to general information sheet for additional
safety precautions and important information.
The two-ball pumps are primarily designed for the pumping of
medium viscosity fluids. The two-ball design provides better
priming of the lower foot valve. The double acting feature is
standard in all ARO industrial pumps. Material is delivered to
the pump discharge outlet on both the up and down stroke.
NOTICE: Thermal expansion can occur when the uid in the mate-
rial lines is exposed to elevated temperatures. Example: Material
lines located in a non-insulated roof area can warm due to sunlight.
Install a pressure relief valve in the pumping system.
Replacement warning label (pn 92325) is available upon re-
quest.
PUMP CONNECTION - UPPER / LOWER
NOTE: All threads are right hand.
Unscrew the lower pump assembly from the air motor.
Pull the air motor from the lower pump end until motor piston
rod is in the “down” position and lower pump end rod is in “up”
position.
Using e-ring pliers, slide the retaining ring up far enough to
allow the sleeve to move upward and release the two connec-
tors.
REASSEMBLY
Align the pump motor with the lower pump end.
y

3.
1.
Install the two connectors and retain with the sleeve, slide the
retaining ring back into position.
Screw the lower pump assembly to the air motor. NOTE: Tight-
en tube to 90 - 100 ft lbs (122.0 - 135.6 Nm).
LOWER PUMP END DISASSEMBLY
NOTE: All threads are right hand.
While holding tube securely with a strap wrench, unthread and
remove foot valve seat.
Remove ball stop pin, releasing ball.
Push piston rod and components out thru the bottom of tube.
Unthread and remove inner check seat, releasing washer, cup
and ball.
Loosen nut to unthread and remove cup follower from piston
rod.
LOWER PUMP END ASSEMBLY
NOTE: Thoroughly clean and lubricate all seals. Replace all soft
parts with new ones included in the repair kit.
Assemble adapter to piston rod. NOTE: Apply Loctite® 242® to
threads of piston rod before assembly.
Assemble nut and cup follower to piston rod, tightening nut
against cup follower. NOTE: Tighten nut to 60 - 70 ft lbs (81.3 -
94.9 Nm).
Assemble cup, washer and ball to cup follower, securing with
inner check seat. NOTE: Tighten inner check seat to 65 - 70 ft
lbs (88.1 - 94.9 Nm).
Assemble “O” ring, ball and ball stop pin to foot valve seat.
NOTE: Assemble pin to farthest hole from ball.
Assemble foot valve seat and components to tube. NOTE:
Tighten foot valve seat to 125 - 150 ft lbs (169.5 - 203.4 Nm).
